Specific embodiment
Embodiment 1
As shown in Figure 1-3, the utility model proposes a kind of cooling system and lithium ion battery mould group integrated system, packet
The cold plate positioned at battery modules side is included, is covered by left cover 305, right cover plate 306；It is covered by left cover 305, right cover plate 306
Cold plate after lid is fixed by front end-plate 101, the end plate 107 of battery modules, and side plate 106 is fixed on the other side of battery, on
Cover board 104 is arranged in the top of battery modules, and heat conductive pad or filling heat-conducting glue, right cover plate are placed between cold plate and battery modules
306 include the convex domain of the storage phase-change material by stamping forming S type inner flow passage 302 and between S type runner
303, cold plate two sides are equipped with the import 102 and outlet 105 that external hose is quickly connected to cold plate, and battery modules rely on front end-plate
101 and the mounting hole of end plate 107 be fixed on inside entire battery pack.Cold plate with a thickness of 0.8mm-1.2mm, held inside cold plate
By an air pressure of 2Mpa.The cold plate uses aluminium material, is bolted on the side of battery modules.Before mould group relies on
The mounting hole of end plate 101 and end plate 107 is fixed on inside entire battery pack.
Liquid cooling plate right panel relies on stamping technology punch forming, while left and right two boards being bonded together using glue, through trying
Number is tested it was demonstrated that the tensile capacity after the cold plate is bonded using glue can reach 66KN, glue can be -45 DEG C to 120 in environment
DEG C use, do not influence the use of cold plate.
Cold plate is bolted on the side of mould group, and the place that cold plate is contacted with mould group side uniformly applies some heat-conducting glues
Or arrangement heat conductive pad etc., it both can guarantee the effect of insulation, while each battery core can also be made effectively to pass the heat of generation
Pass liquid cooling plate.
The technology is needed by selecting reasonable phase transition temperature and suitable thermal management policy come effectively to battery system
System radiates, example: the maximum operation temperature of battery is T0, and the phase transition temperature of phase-change material is T1, thermal management policy: works as battery
When temperature is T2, water pump starting, pump power P1, when battery temperature is T3, water pump pump power increases, pump power P2,
The size relation of middle temperature T are as follows: T1 < T2 < T3 < T0；P1 < P2.
When battery in normal work, and when the temperature of battery reaches T1 this moment, phase transformation, battery takes place in phase-change material
A part of heat generated is stored by phase-change material, and when the temperature of battery reaches T2, water pump starts to start, and liquid cooling is opened
Beginning radiates to battery, and when battery temperature continues to increase, and battery temperature reaches T3, and pump power increases, continues to battery
Temperature control is carried out, during entire heat dissipation, the time that phase-change material makes battery temperature be raised to T2 from the left side T1 is extended, pump
Starting time ratio it is late when there is no a phase-change material, which has reached energy-efficient effect to a certain extent, while can
Effectively to be managed battery system heat.
Liquid cooling plate right panel 103 relies on stamping technology punch forming runner 302 and stores the concave region 303 of phase-change material,
If not only time-consuming also to take a lot of work, left and right two boards are bonded together by this patent using glue using conventional Welding technology,
Do not need soldering, be not influenced by heat by welding before conventional, will not when welding the amount of being deformed, technics comparing is just
Victory, cost is relatively low.
The utility model can make the temperature uniformity of entire battery pack since phase-change material and liquid cooling runner are alternately arranged
More preferably.Above-described embodiment is the preferable embodiment of the utility model, but the embodiments of the present invention is not by above-mentioned reality
Apply the limitation of example, it is made under other any spiritual essence and principles without departing from the utility model change, modification, substitution,
Combination simplifies, and should be equivalent substitute mode, is included within the protection scope of the utility model.
